Overview

Natural gas smart meter can measures the gas flow rate and flow rate by measuring the different propagation time of the ultrasonic pulse in both the forward and reverse directions. This product is suitable for measuring natural gas, not suitable for gas with much impurity content. Natural gas meter is manufactured to be in accordance with European Standard: EN14236-2007. It has the following advantages: high accuracy, high reliability, low pressure loss, wide measurement range, strong anti-interference capability and energy efficiency.

Main Features

1. Is Able to Adapt to M-Bus/LoRa/NB-IoT/GPRS and Other Wireless Communication Mode

2. Internal Valve

3. Long-term Stability, No Mechanical Abrasion, Easy to Maintain

4. Wide Range, High Sensitivity

5. Internal RTC, Functions Such As Tariff Billing and Event Recording

6. Temperature Compensation Function

7. With High Protection Level IP66

8. MID Certification, ATEX Certification

Main Functions

1. Measurement Characteristics: adopt ultrasonic technology, accurate measurement. There is standby power supply in the meter, even when the main power is off, if the valve fails to close normally, it can still count normally.

2. Automatic Detection Function: support power supply voltage detection, cover opening detection, module loss detection, reverse ventilation detection and other functions.

3. System Data Security: gas consumption data can be saved for a long time.

4. Real Time Alarm: in case of ultrasonic sensor failure (i.e. unable to measure normally), the valve will be closed, and the LCD will send an alarm to remind the user. For other alarms, please refer to the diagnosis, analysis and troubleshooting methods of common faults.
